ASSIGNOR TO THE KAWN'EER COMPANY,

OF NILES, MICHIGAN, A CORPORATION OF MICHIGAN VENTILATOR BRACKET Application led June 29,

The present invention relates to ventilator brackets, and more in particular to a novel `means and method of forming the same. y

Among the objects of the invention is. to

provide a novel means and method of rolling and forming ventilator brackets comprising the right and left sections which are attached to opposite sides of a window frame 'or other frame for a closure, said brackets being formed as a unit, and then cut or separated whereby to eliminate all waste in the manufacture thereof.

A further object is to provide'a novel means and method of forming a pair of ventilator brackets from a single sheet of metal, whereby to materially reduce the manufacturing cost and labor necessary in the production. The invention comprehends the forming or rolling of a unitary construction which is later severed or cut on a diagonal line whereby to form a pair of brackets, one for each side of a window frame or other closure.

Another object is to provide a novel construction of ventilator brackets adapted to receive an-d retain 4an element for the deflection of air currents passing through an opening. A still further object is to provide a construction of bracket with a novel retaining means for the ventilator element, whereby the same is heldin an inclined position with reference to the window or other closure adjacent which the ventilator is placed.

Further objects areto provide a construction of maximum simplicity, eiiiciency, economy and ease of operation; and s uch further objects, advantages, and capabilities as w1ll later more fully appear and are inherently possessed thereby.

The invention further resides in the combin-ation, construction, means and method of forming the same, and arrangements ofv parts. illustrated in the accompanying drawing, and while there is shown therein a preferred embodiment, it is to 'be understood that the saine is susceptible .of modification and change, and comprehends other features and constructions, without departing from the spirit of the invention. Y

In the drawing: 50 .,Fig. 1 is a fragmentary view in perspec- 1931. Serial No. 547,560.

vthe numeral 4 referring to a slidable sash mounted in the window frame. The brackets 1 and 2 are adapted to receive and retain a ventllator 5 for lntercepting and deiiecting -air currents passing through the window opening. Although the ventilator construction is shown as mounted on a window frame, it is to be understood that the same may be employed in combination `with any opening or closure therefor, or wherevervdesired. In l the present construction, the ventilator rests upon ,the window sill a.

In the construction of the brackets, the same are formed as a unit 6 provided with oppositely pressed or stamped ribs 7, 8 and 9, and oppositely faced flanges 10 and 11, the inner flange being doubled upon itself for its full extent, and the outer flange 10 being disclosed as doubled upon itself for 'a portion of its length. These flanges 10 and 11 provide a longitudinally extending groove or channel 12 adapted to receive opposite ends of the ventilator 5, and retain the same in position. Suitably spaced openings 13 are provided diagonally through the body of the unit. These openings are adapted to receive screws or other attaching means 14 for attaching each bracket to the frame 3.

After the formation of the embossed portions or ribs 7, 8 and 9, and the iianges 10 and 11, and the openings or screw holes 13, the unit is severed or cut along the line b which is diagonally disposed to the sides thereof, whereby to form a pair of substantially triangular shaped brackets 1 and 2, one to form the left and the otherthe right bracket. By the present method and means of form-T ing the brackets, there is a considerablesavl" 100 ing in the material used and reduction in the manufacturing cost, as well as the labor necessary for such roduction. The channel construction provi es an etlcient and substantially rigld means for retaining the ventilator in position. y

Having thus disclosed the invention, Il claim:

l. The method of manufacturing brackets for ventilators, comprising the steps of forming retaining channels in opposite directions out of the plane of a metal sheet, and cutting the sheet to provide a pair of brackets, each provided with a retaining channel at an edge. thereof.

2. The method of manufacturing brackets for ventilators, comprising the steps of formino` from a sheet of metal, oppositely faced flanges for receiving and retaining a ventilator, and cutting said sheet to provide a pair of brackets, each provided with flanges at an edge thereof.

3. The method of manufacturing brackets for ventilators, comprising the steps of forming retaining channels in opposite directions out of the plane of a metal sheet, and cutting the sheet diagonally and intermediate said channels to provide a pair of brackets, each provided with a retaining channel.

4. The method of constructing brackets for ventilators, comprising the steps of rolling a sheet of metal to form oppositely faced channels and ribs, and cutting said sheet intermediate said oppositely faced channels and ribs to provide apair of brackets.

5. The method of constructing bracketsfor ventilators, comprising the steps of rolling a sheet of metal to form oppositely faced channels, and ribs, and severing said sheet diagonally to provide a pair of brackets, each having a channel at an edge thereof.

6. The method of constructing brackets for ventilators, comprising the Steps of rolling a sheet of metal to form oppositely for receiving and retaining a ventilator, comprisin the steps of deforming a sheet to provi e spaced ribs on opposite sides of said sheet, providing oppositely faced ychannels at the edges of said sheet, and severing said sheet to provide a pair of brackets.

10. A bracket blank, comprising a sheet of metal bent to form oppositely extending channels, said blank being adapted to be severed to form a pair of brackets, each bracket provided with a channel for the reception and retention of an end of a ventilator.

11. A bracket blank, comprising a sheet of metal bent to form oppositely extending ribs and flanges providing a channel, said blank bein adapted to be severed intermediate the c annels and ribs to form a pair of brackets, each provided with a channel for receiving and retaining an end of a ventilator.

`7. The method of constructing from a sheet of metal, brackets for receiving andv retaining a ventilator comprising the'steps of lpressing ribs in said sheet in opposite directions, forming channels at opposite edges of said sheet, and severing saidvsheet intermediate said oppositely extending ribs to provide a pair of brackets.

8. The method of constructing from a sheet of metal, brackets for receiving and retaining a ventilator comprising the steps of pressing ribs in said sheet in opposite dilas rections, forming oppositely faced channels on said sheet and severing said 4sheet dia onally to rovide a pair of brackets eac having a c annel at an edge thereof.
